Re: bitset assignment & copy constructor

So the namespace std could be considered as a set of

considered the same way isolated in his proper namespace "boost". Boost
is just another implementation using the C++ standards and a bit more
extended comparing to the std. (eg more run-time dynamic features)
No. There is a C++ standard, which says what any conforming implementation
must provide. This includes e.g. the parts from the STL and IOStreams, both
contained in the namespace 'std'. Now, the standard doesn't provide any of
the code to achieve that, this is completely left to the compiler vendor.
Further, I wouldn't call Boost an implementation. The point is that for the
C++ standard, you have on one side the standard which defines requirements
and on the other side different compilers and stdlibs from different
vendors that implement this standard. If you look at Boost, you find that
it is a library which doesn't implement a separate standard.
Starting this thread has given me the knowledge to better place all this
C++ and STL stuff as I meanly program in java these days where the
(copy)constructing and assignments are a bit different from C++ ;-)
Actually, if you had mentioned that earlier that you are a Java programmer
that would have helped. Code in 'std' is roughly equivalent to code in
in 'java.*', while the code in 'boost' is something that you get from an
add-on library.
